the games people play

The boys are outside hitting each other with sticks.  And then getting upset because it hurts to get hit with a stick.  There's probably more to this game but I can't really figure it out.  An A+ mom would go outside and explain to them that it's not a good or kind idea to hit each other with sticks.  I, however, think this is an important lesson to learn on one's own.
